Just my opinion, but then, tyou asked for opinions, so here goes. I have followed your posts/updates since joining here and another site. The common thread seems to be a lack of technical support and clear instructions on operation of the various controllers. I think you are on the right track in trying to find someone in the United States to help develop and market here. I, and many others are hesitant to send money overseas as there is a not much recourse if you do not recieve your items along with the impatience of waiting on it to arrive. An example is me, if I buy something, I want it in the next 2 or 3 days, so ideally, they need to be available to ship from the US, IMO.
I know that isn't much help. Good luck...
